A novel multi-layer framework for modeling the evolution of spectrum markets and cognitive-radio devices

Abstract

This work presents a novel multi-layer modelling framework for the evolution of spectrum markets of multiple spectrum/network operators that provide wireless access to users. It integrates models of the channel, mobility, user preference, network operators (providers), infrastructure deployment, user distribution, and price-adaptation mechanisms. Providers aim to maximize their own profit, while clients decide based on criteria, such as the financial cost of the access, transmission rate, and required transmission power. This paper gives a brief description of the modelling framework and a novel price-adaptation algorithm for providers. It presents how this framework can be used to instantiate a cellular-based market in a small city. Finally, it analyzes the evolution of this market under different topologies and user profiles, summarizing the main performance results.
